I am hosting PiBBS on the default telnet port (23) and, as you can imagi I'm getting a lot of...shall we say...unwanted traffic. By default, Myst doing a pretty good job of banning the ones that are actively trying to brute-force the login.
Yeah I have both port 22 and 23 for mystic. Im getting rammed with logins.
But what I did is:
- Auto whitelist logged in users
- Ban on 4 failed attemps in 2 minutes
That seems to keep the bruteforces at a minimum. I do not like to change the port as I do not believe in security by obscurity.
oP!
